RESUMO

BACKGROUND: Sensitive measures to predict neuromotor outcomes from data collected early in infancy are lacking. Measures derived from the recordings of infant movement using wearable sensors may be a useful new technique. METHODS: We collected full-day leg movement of 41 infants in rural Guatemala across 3 visits between birth and 6 months of age using wearable sensors. Average leg movement rate and fuzzy entropy, a measure to describe the complexity of signals, of the leg movements' peak acceleration time series and the time series itself were derived. We tested the three measures for the predictability of infants' developmental outcome, Bayley Scales of Infant and Toddler Development III motor, language, or cognitive composite score assessed at 12 months of age. We performed quantile regressions with clustered standard errors, accounting for the multiple visits for each infant. RESULTS: Fuzzy entropy was associated with the motor composite score at the 0.5 quantiles; this association was not found for the other two measures. Also, no leg movement characteristic was associated with language or cognitive composite scores. CONCLUSION: We propose that the entropy of leg movement associated peak accelerations calculated from the wearable sensor data collected for a full-day can be considered as one predictor for infants' motor developmental outcome assessed with Bayley Scales of Infant and Toddler Development III at 12 months of age.

RESUMO

AIM/BACKGROUND: Both mental maternal health and breastfeeding difficulties impact maternal and infant health. The present study analyses the association between psychosocial and breastfeeding variables and maternal mental health. DESIGN/METHODS: The participants were 107 first-time mothers from Chile. Sociodemographic variables and breastfeeding difficulties were assessed at 6 weeks postpartum. Depression and anxiety symptoms, parental self-efficacy, and perceived social support were measured using validated, self-report questionnaires at 6 weeks and 5 months postpartum. This study is a secondary analysis of an intervention trial. RESULTS: 76% of the women reported having experienced some breastfeeding difficulty in the first postpartum weeks. The number of breastfeeding difficulties was associated with maternal mental health symptoms at 6 weeks postpartum and parental self-efficacy at both assessment times. Women who did not experience breastfeeding difficulties presented significantly fewer depressive (t(102) = 2.5, p = .015) and anxiety symptoms (t(50) = 2.3, p = .028) at 6 weeks postpartum than those who did. Mothers who exclusively breastfed at 5 months postpartum presented significantly higher parental self-efficacy (t(94) = 2.4, p = .044). A higher number of breastfeeding difficulties and low perceived social support contributed to higher depressive symptoms (R2 = .30; F(3,103) = 14.6, p < .001), anxiety symptoms (R2 = .32, F(3.103) = 17.27, p < .001) and lower parental self-efficacy at 6 weeks postpartum (R2 = .39; F(2,103) = 9.4, p < .001). CONCLUSION: Breastfeeding difficulties and social support are associated with fewer mental health symptoms and higher parental self-efficacy during early postpartum in first-time mothers.

RESUMO

OBJECTIVE: This study aims to investigate the relationship between the Developmental Surveillance Instrument -Instrumento de Vigilância do Desenvolvimento (IVD), found in the Child's Booklet Caderneta da Crianca (CC), and standardized scales: Alberta Infant Motor Scale (AIMS) and Denver Developmental Screening Test (Denver-II). METHODS: Employing an exploratory observational approach, we adopted a prospective longitudinal design with a quantitative approach. The convenience sample included 83 Brazilian children born between May and August 2019 in a public hospital. Of the total, 45 (54.22 %) were male, and 38 (45.78 %) were female. Developmental screening utilized the IVD, AIMS and Denver-II tests. Comparative analysis between groups employed Mann-Whitney or Kruskal-Wallis tests for numerical variables and chi-square/Fisher tests for categorical variables, with a significance level of 5 % (p < 0.05). RESULTS: A significant correlation was observed between the IVD and the AIMS and Denver-II tests (p < 0.001) at months 1, 4, and 8. CONCLUSION: The presence of a robust correlation between the IVD and the AIMS and Denver-II tests at months 1, 4, and 8 implies that the IVD in the Child's Booklet serves as a reliable and effective indicator for screening infant development during this critical period. Detecting issues early through these methods is crucial to ensure the well-being of children, allowing for appropriate interventions as needed.

RESUMO

Introduction. Brazil's health system offers insights into addressing the double burden of malnutrition by proper population monitoring, coupled with local policies and national guidelines. Objective. To investigate the recent temporal trends in nutritional status indicators and its coverage of children aged two to five years from Campinas, a metropolis in the state of São Paulo, Brazil. Material and methods. The analysis of time series from 2018 to 2022 were conducted by accessing data from the Brazilian Food and Nutrition Surveillance System (SISVAN) due to regression analysis. Results. The number of children aged two to five in the SISVAN registry rose from 7,300 in 2018 to 11,171 in 2022, forming the study sample. In 2018, 700 were chronically undernourished, 306 underweight, and 977 overweight; by 2022, 530 showed stunting, 457 were underweight, and 1,084 overweight. Stunting prevalence declined from 9.6% (2018) to 4.7% (2022). Underweight dropped slightly from 4.2% to 4.1% over the years and overweight, consistently the highest indicator, ranged from 13.4% (2018) to 9.7% (2022). SISVAN's coverage varied between 16.6% (2018) and 26.1% (2022), the lowest at 12.3% in 2020. The trend for stunting decreased significantly (APV: -15.01; CI95% -22.64; -6.62). Adding SISVAN's coverage variable the model slightly reduced the declining stunting trend (APV: -12.12; CI95% -13.19; -11.04). Conclusions. Coordinated efforts to address nutritional challenges, from adequate population monitoring to the interaction between local policies and national guidelines, have shown positive health outcomes(AU)

RESUMO

Purpose: To investigate the risk of global developmental delay in infants born from mothers with COVID-19. Patients and Methods: A cross-sectional study was conducted between March and November 2021, with 54 infants of both sexes aged between 1 and 12 months. Twenty-seven infants born from mothers diagnosed with COVID-19 during pregnancy composed the COVID-19 group, whereas infants born from mothers not exposed to COVID-19 composed the control group. Medical records and child health booklets provided neonatal and prenatal data. The Survey of Wellbeing of Young Children screened the risk of global developmental delay during a phone interview or home visit. Chi-squared, Mann-Whitney test, and binary logistic regression were applied. Results: The risk of motor developmental delay was identified in 15 infants (12 in the COVID-19 group), while 36 were at risk of behavioral alteration (22 in the COVID-19 group). The COVID-19 group presented a 6.3-fold risk of motor developmental delay. Motor developmental delay was also significantly associated with socioemotional alterations (odds ratio = 6.4, p = 0.01). Regarding families of infants in the COVID-19 group, 63% of the mothers presented risk of depression, 51.9% risk of substance abuse, 40.7% risk of food insecurity, and 7.4% risk of domestic violence. The inflexibility subscale of the survey was a statistically relevant variable for the socioemotional domain. Conclusion: Infants born from mothers with COVID-19 were at high risk of motor developmental delay and socioemotional alterations. Although, this study fills an important gap in the literature regarding the influence of maternal exposure to COVID-19 on infant development, new studies screening families with infants at risk of developmental delay may significantly impact maternal and child health-related indicators, such as physical health, emotional development and social behavior.

RESUMO

BACKGROUND: Deviations occur in the neuropsychomotor development of premature infants; early interventions minimize delay motor. This study aimed to determine the effect of an interdisciplinary hospital-home intervention addressing motor development adaptation in premature infants in Colombia in comparison with traditional interventions. METHODS: This study was based on a parallel design, with two groups, namely, experimental and control. The experimental group, hospital-home intervention (HHI) performed in two settings (i.e., hospital neonatal care units and homes), and the control group, traditional intervention, (TI) performed in institutions for premature infants. The sample will be composed of 130 randomly-allocated infants, 65 in the experimental group (HHI) and 65 in the control group (TI) of moderate to late preterm infants (gestational age between 34 and 37 weeks), weighing more than or equal to 1.800 g, who are hemodynamically stable and reside in the cities of Tunja and Bogotá-Colombia recruited between 2021 and 2022. For the pre- and post-intervention assessments, the TIMPSI and the CapDMP are the instruments used to assess motor development and the degree of parents' or caregivers' knowledge about motor development. The HHI is composed of 10 intervention strategies based on stimulation of motor development, performed twice a day for 10 min for two months, in combination with calls to a mobile device, using software (Baby Motor Skills) and an instant messaging system (WhatsApp). RESULTS: This hospital-home intervention program proposes an approach focused on the motor development of premature infants, based on sensory and motor stimulation strategies, in addition to follow-up performed at home with the use of a mobile application that improves the motor development of premature infants. Register Clinical Trial: NCT04563364. CONCLUSION: The HHI provides the opportunity to determine whether the individualized four-week from admission to follow up at home with parent training will improve the motor skills of premature infants.

RESUMO

PURPOSE: The primary aim will be to assess the effects of prone positioning (tummy time) on cervical extension (angular kinematics and time) in preterm infants. The secondary aim will be to assess the effects of tummy time on gross motor function. METHODS: This randomized, controlled clinical trial will include 40 preterm infants weighing less than 2500 g, randomly allocated into control or experimental group (n = 20) and followed up from birth to six months of corrected age by the team of the neonatal follow-up clinic. Caregivers will be routinely guided on bonding, developmental milestones, and how to perform the tummy time for 30 min throughout the day (experimental group). An illustrative booklet will be provided as support material. The hypothesis will be tested using inferential analysis, considering an alpha of 5%. DISCUSSION: We expect tummy time to strengthen cervical muscles needed to overcome gravity, master motor skills, and stimulate the integration between family activity and environmental experiences, considerable challenges to which preterm infants are exposed. TRIAL REGISTRATION: Registered in the Brazilian Registry of Clinical Trials (identifier RBR-2nwkr47) on 17 February 2022.

RESUMO

INTRODUCTION: Studies on maternal microRNA expression have emerged to better understand regulatory mechanisms during the gestational period, since microRNA expression has been associated with pregnancy disorders. OBJECTIVES: This study aims to investigate the association between the expression of the maternal microRNAs miR-let-7d-3p and miR-451a during the second gestational trimester and neuropsychomotor development at 90 days of life of infants. METHODS: This is a case-control study nested within a cohort, with the groups being divided into dyads in which pregnant women presented Major Depressive Episode (MDE) (n = 64), these being the cases, and their respective controls (no MDE; n = 64). The Bayley Scale III was used to assess the outcome of child development, and MDE was assessed through the Mini International Neuropsychiatric Interview Plus. The analysis of miR-let-7d-3p and miR-451a was done via serum from the pregnant women, utilizing the qRT-PCR (n = 128). RESULTS: The results indicated a negative association between expression levels of miR-451a (ß -3.3 CI95% -6.4;-0.3) and a positive associated of the miR-let-7d-3p with the cognitive development domain (ß 1.7 CI95% 0.1; 3.0), and a positive association between expression of miR-let-7d-3p with motor development of the infants (ß 1.6 CI95% 0.3; 2.9). CONCLUSION: This is a pioneering study on the topic that indicates a biological interrelationship between the miRNAs miR-let-7d-3p and miR-451a evaluated during the pregnancy and the motor and cognitive domains of infant development at 90 days postpartum.

RESUMO

OBJECTIVE: To evaluate the predictive relationship between early trajectories of postural and head control during a pull-to-sit task and later autism diagnostic and developmental outcomes. STUDY DESIGN: Using a prospective longitudinal design, postural skills of 100 infants at elevated and low familial likelihood of autism spectrum disorder (ASD) were evaluated using a pull-to-sit task monthly from age 1 month to 6 months. At age 24 months, infants were seen for a developmental and diagnostic evaluation completed by examiners masked to participant group. Latent growth curve models were used to compare early trajectories of pull-to-sit performance in infants later diagnosed with ASD and typically developing infants and to predict developmental outcomes. RESULTS: Pull-to-sit trajectories did not differ in infants with an elevated likelihood of ASD or infants with ASD compared with low-likelihood and typically developing infants, but infants with ASD were more likely to exhibit a head lag by age 4 months. In addition, pull-to-sit trajectories were predictive of social and speech skills 2 years later. CONCLUSIONS: These findings highlight the link between very early pull-to-sit skills and later social and language outcomes. Atypical postural development and persistent presence of head lag may be important early indicators of social and language vulnerabilities, including ASD.

RESUMO

BACKGROUND: Over 250 million children under 5 years, globally, are at risk of developmental delay. Interventions during the first 2 years of life have enduring positive effects if children at risk are identified, using standardized assessments, within this window. However, identifying developmental delay during infancy is challenging and there are limited infant development assessments suitable for use in low- and middle-income (LMIC) settings. Here, we describe a new tool, the Oxford Neurodevelopment Assessment (OX-NDA), measuring cognition, language, motor, and behaviour, outcomes in 1-year-old children. We present the results of its evaluation against the Bayley Scales of Infant Development IIIrd edition (BSID-III) and its psychometric properties. METHODS: Sixteen international tools measuring infant development were analysed to inform the OX-NDA's construction. Its agreement with the BSID-III, for cognitive, motor and language domains, was evaluated using intra-class correlations (ICCs, for absolute agreement), Bland-Altman analyses (for bias and limits of agreement), and sensitivity and specificity analyses (for accuracy) in 104 Brazilian children, aged 12 months (SD 8.4 days), recruited from the 2015 Pelotas Birth Cohort Study. Behaviour was not evaluated, as the BSID-III's adaptive behaviour scale was not included in the cohort's protocol. Cohen's kappas and Cronbach's alphas were calculated to determine the OX-NDA's reliability and internal consistency respectively. RESULTS: Agreement was moderate for cognition and motor outcomes (ICCs 0.63 and 0.68, p < 0.001) and low for language outcomes (ICC 0.30, p < 0.04). Bland-Altman analysis showed little to no bias between measures across domains. The OX-NDA's sensitivity and specificity for predicting moderate-to-severe delay on the BSID-III was 76, 73 and 43% and 75, 80 and 33% for cognition, motor and language outcomes, respectively. Inter-rater (k = 0.80-0.96) and test-rest (k = 0.85-0.94) reliability was high for all domains. Administration time was < 20 minutes. CONCLUSION: The OX-NDA shows moderate agreement with the BSID-III for identifying infants at risk of cognitive and motor delay; agreement was low for language delay. It is a rapid, low-cost assessment constructed specifically for use in LMIC populations. Further work is needed to evaluate its use (i) across domains in populations beyond Brazil and (ii) to identify language delays in Brazilian children.

RESUMO

Background: Social withdrawal is a risk indicator for infant development with both organic and non-organic causes. Cleft lip and palate (CLP) impose a higher risk of physical and emotional distress in infants and alters parent-infant relationships. The ADBB scale is a screening tool to identify social withdrawal as a sign of distress in infants. The aim of this study is to evaluate the prevalence of social withdrawal behavior in infants with CLP using the full 8-item ADBB scale and the modified 5-item ADBB scale, and to examine the feasibility of both scales. Methods: 145 infants with Cleft Lip and Palate were enrolled and video recorded during a pediatric consultation. All infants were scored by two expert raters trained in ADBB scale, and subsequently scored with the m-ADBB by an independent expert. We measured the interrater agreement for the full ADBB scale and psychometric properties of both scales. Results: The full ADBB scale identified 15.9% of infants as having social withdrawal behavior (score above cutoff ≥5). Among the infants evaluated with the m-ADBB scale, 44.9% had a score above the suggested cutoff (≥2). For both scales, the item "vocalization" showed the higher scores. We found a good internal consistency for the full ADBB (Cronbach's alpha = 0.82) and an acceptable internal consistency for the modified ADBB (Cronbach's alpha = 0.71). The interrater agreement for the full ADBB scale was excellent (kappa = 0.837). The Spearman correlation coefficient between the total scores of the two versions was 0.88 (P < 0.001). Conclusion: Our results indicate a relatively high prevalence of social withdrawal in infants with Cleft Lip and Palate, especially evaluated with the modified 5-item ADBB scale. We found that the full ADBB and the modified ADBB scales are feasible to use as screening tools of social withdrawal in this population. Clinical Trial Registration: This trial is registered on ClinicalTrials.gov, identifier: NCT00993993. The data is the property of Assistance Publique, Hôpitaux de Paris.

RESUMO

As interações sociais iniciais são fundamentais para o desenvolvimento infantil, sendo essencial o papel dos adultos na promoção de práticas que o favoreçam. Tais práticas podem ser influenciadas por aspectos contextuais e pelas emoções, concepções e expectativas parentais sobre seus filhos. No presente estudo, foi considerada a configuração familiar caracterizada pela presença de bebês gêmeos. O objetivo foi conhecer as emoções das mães acerca da gravidez gemelar e analisar as suas concepções e expectativas sobre o desenvolvimento dos gêmeos nos primeiros 24 meses de vida. Participaram deste estudo nove mães de bebês gemelares, que responderam a um questionário sociodemográfico e a uma entrevista semiestruturada. Os resultados revelaram sentimentos maternos ambivalentes relativos à experiência com a gemelaridade desde a gestação; concepções sobre desenvolvimento infantil, fatores que podem influenciá-lo e diferenças entre os gêmeos; e expectativas sobre o desenvolvimento dos bebês. Conclui-se que uma maior compreensão sobre aspectos relacionados à maternidade de gemelares pode auxiliar na criação de redes de apoio socioemocional aos cuidadores e de contextos que favoreçam as interações estabelecidas entre a tríade mãe-bebês.

Initial social interactions are fundamental to child development, and the role of adults in promoting practices that favor them is essential. Such practices can be influenced by contextual aspects and by parental emotions, conceptions and expectations about their children. In the present study, the family configuration characterized by the presence of twin babies was considered. The objective was to get to know the mothers' emotions about twin pregnancies and to analyze their conceptions and expectations about the development of twins in the first 24 months of life. Nine mothers of twin babies participated in this study, who answered a sociodemographic questionnaire and a semi-structured interview. The results revealed ambivalent maternal feelings regarding the experience with twinning since pregnancy; conceptions about child development, factors that can influence it and differences between twins; and expectations about the development of babies. We conclude that a greater understanding of aspects related to twin maternity can help in the creation of social and emotional support networks for caregivers and contexts that favor the interactions established between the mother-babies triad.

RESUMO

OBJECTIVES: To verify the agreement between the Alberta Infant Motor Scale assessment and maternal perception of the motor development in full-term infants. METHODS: This is a cross-sectional study involving 161 infants and mothers. Children were assessed with the Alberta Infant Motor Scale (AIMS) for motor developmental classification. Mothers completed questionnaires aiming to identify maternal profiles and impressions about their children's development. The kappa test was used to analyze the concordance between AIMS and mother perceptions. RESULTS: A total of 83.2% of the sample was classified as typically developing and 16.8% as suspected or delayed development. The maternal impression indicates that 77% of infants are developing typically, 19.9% perceived their infants' development as advanced, and 3.1% delayed development. There was low agreement between the mothers' perceptions and AIMS classifications (kappa = 0.153). CONCLUSIONS: Maternal perception of their infant's development was unsatisfactory for evaluation of motor development because their perceptions did not agree with the findings of the AIMS.

RESUMO

OBJECTIVE: To evaluate the outcome of food intake and nutritional status post discontinuation of a cow's-milk-free diet after a negative oral food challenge. METHODS: This was a prospective, uncontrolled study that evaluated food intake and nutritional status of a cohort of 80 infants and children under 5 years of age. Food intake and nutritional status were evaluated on the day of the oral food challenge test and after 30 days. Weight and height were measured on the day of the test and after 30 days. RESULTS: The mean age of the patients was 18.7 ± 12.4 months, and 58.7% were male. After discontinuation of the elimination diet, the children showed daily intake increases in (P < 0.001), protein (P < 0.001), carbohydrates (P = 0.042), calcium from foods (P < 0.001), calcium from foods and supplements (P < 0.001), phosphorus (P < 0.001), and vitamin D from foods (P = 0.006). The Z-scores (n = 76) on the day of the oral food challenge test and 30 days after restarting the consumption of cow's milk were as follows: weight-for-age (P < 0.001) and height-for-age (P < 0.001), respectively. CONCLUSION: Cow's milk protein in the diet was associated with increased intake of energy, proteins, carbohydrates, calcium, phosphorus, and vitamin D, in addition to an increase in the Z-scores for weight-for-age and height-for-age.

RESUMO

This study compared children's and mothers' digital media use and mothers' mental health in two samples: one accessed before (Group 1; N = 257; M = 33.18 years; SD = 4.79) and the other accessed during (Group 2; N = 256; M = 33.51 years; SD = 4.96) the COVID-19 pandemic in Brazil. Mothers of children up to 3 years old (Group 1: M = 17.95 months, SD = 9.85; Group 2: M = 16.48 months, SD = 10.15) answered an online survey. Bivariate analysis, factorial ANOVA tests, and multiple linear regression were performed. Results suggest that mothers' and children's media use duration was higher during the pandemic only among children over 12 months. Mothers' media use duration (ß = .18) and mothers' intention to offer media (ß = .23) contributed to the explanation of children's media use duration (F(4, 474) = 16.81; p < .001; R2  = .12; R2 adjusted = .117). Higher mothers' common mental disorders symptoms were also positively correlated to mothers' intention to offer media to children both before and during the pandemic. Results suggest that interventions focusing on infants and toddlers screen time reduction should target maternal aspects such as mental health, maternal screen time, and intention to offer media, taking into account the mothers' needs when planning these actions.

Este estudio comparó el uso de los medios digitales por parte de los niños y las madres con la salud mental de las madres en dos grupos muestra: uno al cual se tuvo acceso antes (Grupo 1: N = 257; M = 33.18 años; SD = 4.79) y el otro al cual se tuvo acceso durante (Grupo 2; N = 256; M = 33.51 años; SD = 4.96) la pandemia del COVID-19 en Brasil. Las madres de niños de hasta tres años (Grupo 1: M = 17.95 meses, SD = 9.85; Grupo 2: M = 16.48 meses, SD = 10.15) respondieron una encuesta electrónica. Los análisis bivariados los exámenes factoriales ANOVA, así como múltiples regresiones lineales se llevaron a cabo. Los resultados indican que la duración de uso de los medios por parte de las madres y los niños fue más alta durante la pandemia sólo entre niños de más de 12 meses. La duración de uso de los medios por parte de las madres (ß = 0.18) y la intención de las madres de ofrecer los medios (ß = 0.23) contribuyeron a explicar la duración de uso de los medios por parte de los niños (F(4,474) = 16,81; p < .001; R2 = .12; R2 ajustado = .117). Más altos síntomas de trastornos mentales comunes en las madres se correlacionaron también positivamente con la intención de las madres de ofrecer los medios a los niños tanto antes como durante la pandemia. Los resultados indican que las intervenciones enfocadas en reducir el tiempo frente a la pantalla de infantes y niños pequeñitos deben dirigirse a los aspectos maternos como la salud mental, el tiempo de la madre frente a la pantalla, así como la intención de ofrecer los medios, tomando en cuenta las necesidades de las madres cuando se planeen estas acciones.

Cette étude a comparé l'utilisation des médias numériques des enfants et des mères et la santé mentale des mères chez deux échantillons: l'un accédé avant la pandémie du Covid-19 (Groupe 1; N = 257; M = 33,18 ans; SD = 4,79) et l'autre accédé durant la pandémie du covid-19 (Groupe 2; N = 256; M = 33,51 ans; SD = 4,96) au Brésil. Les mères d'enfants jusqu'à l'âge de trois ans (Groupe 1: M = 17,95 mois, SD = 9,85; Groupe 2: M = 16,48 mois, SD = 10,15) ont répondu à un questionnaire en ligne. Une analyse à deux variables, des tests ANOVA factoriels, et une régression linéaire multiple ont été faits. Les résultats suggèrent que la durée de l'utilisation média des mères et des enfants a été plus élevée durant la pandémie uniquement pour les enfants de plus de 12 mois. La durée de l'utilisation média des mères (ß = 0,18) et l'intention des mères à offrir le média (ß = 0,23) a contribué à l'explication de la durée de l'utilisation média des enfants (F(4, 474) = 16,81; p <,001; R2 = ,12; R2 adjusté = ,117). Plus de symptômes communs de troubles mentaux des mères était aussi lié de manière positive à l'intention des mères d'offrir le média à la fois avant et durant la pandémie. Les résultats suggèrent que les interventions s'attachant à la réduction du temps d'écran des bébés et des petits enfants devraient cibler des aspects maternels comme la santé mentale, le temps d'écran maternel, et l'intention d'offrir le média, prenant en compte les besoins des mères en planifiant ces actions.

RESUMO

In recent decades, music therapy in the Neonatal Intensive Care Unit (NICU) has been shown to regulate preterm infant's physiological responses and improve maternal mental health. This study investigated the effects of the music therapy intervention for the mother-preterm infant dyad (MUSIP) for maternal anxiety, postnatal depression, and stress, and preterm infants' weight gain, length of hospitalization, heart rate (HR), and oxygen saturation (So2 ). A pre-experimental design was used with 33 mother-preterm infant dyads in a Brazilian NICU: 16 dyads in the Music Therapy Group (MTG) and 17 dyads in the Control Group (CG). The MTG took part in the MUSIP, aimed at supporting maternal singing with the preterm baby. Infants' HR and So2 were recorded at each minute from 10 min before to 10 min after sessions 1, 3, and 6. Before infants' discharge, maternal anxiety and depression scores were lower in the MTG compared to the CG. Anxiety, depression, and stress levels decreased significantly after the intervention in the MTG. With regard to infants, HR and So2 ranges were higher during music therapy, compared to before and after sessions. MUSIP improved maternal mental health and affected preterm infants' emotional arousal, with positive trends in decreasing HR, stabilizing So2 , and reducing length of hospitalization.

En décadas recientes, la terapia musical de la Unidad de Cuidados Intensivos Neonatales ha demostrado poder regular las respuestas fisiológicas del infante nacido prematuramente y mejorar la salud mental materna. Este estudio investigó los efectos de la Intervención de Terapia Musical para la Díada Madre-Infante Prematuro (MUSIP) en cuanto a la ansiedad materna, la depresión posnatal y el estrés, así como el aumento del peso de los infantes prematuros, el tiempo de hospitalización, el ritmo cardíaco (HR) y la saturación de oxígeno (SO2). Un diseño preexperimental se usó con 33 díadas de madre-infante prematuro en una Unidad brasileña de Cuidados Intensivos Neonatales: 16 díadas en el Grupo de Terapia Musical (MTG) y 17 díadas en el Grupo de Control (CG). El MTG participó en MUSIP, con la finalidad de apoyar el canto materno con el bebé prematuro. Se anotó el HR y SO2 de los infantes en cada minuto a partir de 10 minutos antes hasta 10 minutos después de la Sesión 1, 3 y 6. Antes de darles de alta a los infantes, se redujeron los puntajes de ansiedad y depresión maternas en el MTG tal como se le comparó con el CG. Los niveles de ansiedad, depresión y estrés se redujeron significativamente después de la intervención en el MTG. Con respecto a los infantes, los intervalos de HR y SO2 fueron más altos durante la terapia musical, tal como se les comparó con los momentos antes y después de las sesiones. MUSIP ayudó a mejorar la salud mental materna y afectó el despertar emocional de los infantes prematuros, con tendencias a reducir el HR, estabilizar el SO2 y reducir el tiempo de hospitalización.

Dans les vingt et trente dernières années, il a été démontré que la thérapie musicale en Réanimation Néonatale régule les réponses physiologiques du bébé prématuré et améliore la santé mentale maternelle. Cette étude a étudié les effets de l'Intervention de Thérapie Musicalepour la dyade Mère-Bébé Prématurés (MUSIP) pour l'anxiété maternelle, la dépression postnatale, et le stress, ainsi que la prise de poids des bébés prématurés, la longueur de l'hospitalisation, le rythme cardiaque (RC ici) et la saturation d'oxygène (sO2). Une structure pré-expérimentale a été utilisée avec 33 dyades mère-nourrisson prématuré dans une Réanimation Néonatale au Brésil: 16 dyades dans le Groupe Thérapie Musicale (GTM en français) et 17 dyades dans le Groupe de Contrôle (GC en français). Le groupe GTM a pris part à la MUSIP, destiné à aider et soutenir les mères à chanter avec leur bébé prématuré. Le RC et la sO2 des nourrissons ont été enregistrés à chaque minute pendant 10 minutes avant jusqu'à 10 minutes après la Session 1, 3, et 6. Les scores d'évacuation des nourrissons, de l'anxiété maternelle et de dépression maternelle étaient moins élevés dans le GTM que dans le GC. L'anxiété, la dépression et les niveaux de stress ont baissé de manière importante durant l'intervention dans le groupe GTM. Pour ce qui concerne les nourrissons, les éventails de RC et de sO2 était plus élevés durant la thérapie musicale, comparés à avant et après les sessions. La MUSIP a amélioré la santé mentale maternelle et affecté la stimulation émotionnelle des nourrissons prématurés, avec des tendances positives dans la baisse du RC, la stabilisation sO2 et la réduction de la longueur de l'hospitalisation.

RESUMO

This study longitudinally examined the interplay between birth-order and well-known risk factors in impoverished environments such as inadequate environmental stimulation, low maternal education, and young maternal age in children from birth to 36 months. In the developmental motor domain, the effect of the stimulating environment over time, favored first-borns. In the adaptive domain, maternal education privileged first-born boys. In language development, first-borns reached higher scores over time than laterborn identifying a positive impact of stimulation. In the personal-social domain, firstborns obtained higher averages overall, but stratified models revealed that later-borns reached the first-borns scores as maternal age increased.

RESUMO

La displasia del desarrollo de la cadera comprende un conjunto de anormalidades que afectan la articulación coxofemoral: la displasia, subluxación y luxación de la cadera. El concepto de "displasia" describe anormalidades en la estructura femoral, acetabular o ambas. Corresponde a la patología ortopédica más frecuente del recién nacido y lactante, lo que genera mucha preocupación e intranquilidad entre los padres, en los primeros controles sanos de sus hijos. Es una patología en la que un diagnóstico oportuno y precoz son la clave para poder realizar un tratamiento efectivo, obteniendo como resultado una cadera clínica y radiológicamente normal al finalizar el desarrollo esquelético. Para esto es fundamental conocer la patología e ir activamente en su búsqueda. Actualmente existe mucha discusión sobre la manera de pesquisar esta patología. En Chile, se realiza tamizaje universal con imagen -radiografía de pelvis- a todos los niños a los 3 meses de edad. El objetivo de la siguiente revisión, es traer a la práctica clínica actual de todos aquellos profesionales que se enfrentan en distintos escenarios a esta patología: médicos de atención primaria, enfermeras, médicos en etapas de destinación y formación en distintas regiones del país, pediatras y ortopedistas, aquellas características y signos de sospecha propios de esta enfermedad y detallar las herramientas para un correcto diagnóstico y oportuno tratamiento.

Developmental dysplasia of the hip (DDH) comprises a set of abnormalities that affect the hip joint: hip dysplasia, subluxation, and dislocation. It is the most frequent orthopedic pathology of the newborn and infant, and it generates great concern among parents during the first health check-ups of their children. It is a condition in which a timely and early diagnosis is key to be able to carry out an effective treatment, obtaining as a result of a clinically and radiologically normal hip at the end of skeletal development. For this, it is essential to know this orthopedic condition and actively search for it. Currently, there is much discussion about how to screen DDH. In Chile, universal screening with imaging - pelvic radiography - is performed on all children at 3 months of age. The objective of the following review is to bring to the current clinical practice of all those professionals who face this pathology in different scenarios: primary care physicians, nurses, physicians in training stages in different regions of the country, pediatricians and orthopedic surgeons, signs of suspicion typical of the disease and detail the assessment tools for a correct diagnosis and timely treatment.
